We compared the nucleotide sequences of 3 yeast invertase genes in regions where the homology is better than 90%. In the noncoding region 40 gaps of 1-61 bases were found. This is about half as much as the nucleotide substitutions in the same sequences. We grouped the gaps into 5 categories by their length and the characteristics of their sequences. Group I gaps are about 20 nucleotides long and are flanked by repeated sequence of 6 bases which may trigger the deletion of one of the repeats and the sequence between the repeats. Group II gaps are characterized by a small repeated sequence which is missing in one of the invertase genes. Gaps which occur in sequences exclusively made up of one of the 4 bases are summarized in group III. The 4 gaps in group IV do not show any of these sequence characteristics and they are all just one base long. A 61 nucleotide sequence found in only one of the invertase genes seems to be of complex origin. We conclude that small repeated sequences or monotonous sequences are prone to deletion or insertion mutations.
